2, Figures 2,7 and 14, represents a number of dials which register the total of the numbers which are added together. These dials consist preferably of cup-shaped wheels which are numbered on their peripheries and are mounted intheir proper order on a transverse dial shaft 3, which is journaled in bearings on the main frame, the dials being so arranged that the dial representing the lowest number is arranged on the right hand end of the series and the dials representing the successively higher numbers being arranged successively in their order toward the left from the dial representing the lowest number. The lowest or right hand dial is preferably divided on its periphery into one-eighths so as to indicate fractions of a cent in eighths, and the remaining dials are graduated on their periphery according to the decimal system into tenths. As shown in the drawings ten total dials are shown and extend from fractions of a cent to tens of millions, but if desired, additional dials may be added to the right and to the left of the series, if it is desired to register smaller divisions of a cent or more than tens of millions. Each of the dials 2 is provided on its left-hand side with a gear pinion 4, which is rigidly connected therewith, as shown in Figures 2, 7 and 14. The pinion of the fraction wheel has eight teeth while the pinions of the remaining dials are each provided with ten teeth. 5 represents the registering gear segments, one of which is provided for each of the dials 2 and is adapted to engage with the pinion thereof, for operating the respective dial; Each of these gear segments is arrangedin rear of its companion gear pinion and is provided at its lower end with a rearwardly projecting arm 6 which is pivoted loosely on a transverse supporting rod 7L This rod is mounted with its ends on the upper ends of two rock arms 8 which turn loosely with their lower ends on a transverse rock-shaft 9. The rod-arms 8 ,are connected by a transverse bar 10 which these spaces being in line withthe pivots of the pinions and the gear segments.

machine.

The gear segments are yieldingly held backwardly-out of engagement with the dial pinions by means of springs 11 (Fig. 10) connecting the rock-arms 8 with a stationary part of the frame. Figure 10 shows one of the springs 11 conmeeting-one of the rock-arms 8 with a transverse stationary bar 12 in the rear part of the The gear segments are moved forwardly so that their teeth engage with the dial pinions 4 by means of a shifting rock arm 13 (Fig. 2), which is preferably secured to the right hand rock-arm 8. and: projects rearwardly. Upon raising the shifting rock,- arm 13, the rock-arms 8 are swung forwardly and the gear segments 5 are engaged with the dial pinions, while upon swinging the shifting rock-arms downwardly, the rock-arms 8 are swung readwardly and the gear segments are disengaged from the dialpinions. 14 represents a cam whereby the gear segments are engaged with the dial pinions.

This cam is mounted on. the upper portion of a vertically swinging rocking frame 15 which is arranged on the right hand side of the ma; chine. This cam is provided at itsfront end with an incline or cam face 16 and at its rear end with a concentric face-17. When the cam is in its rearmost or retracted position, its incline stands in rear of a roller or projection 18 on the rear end of the shifting arm 13, as shown in Figures 2, 7 "and 15. Upon swinging the rocking frame 15, so that .the cam 14 moves forwardly. the incline of the latter engages underneath the roller 18 and raises the arm 13, thereby moving the arms 8 forwardly. The throw of the incline 16 is just suflicient to engage the teeth of the gear segments with the dial pinions. When the roller 18 has been raised to the top of the incline, the concentric portion of the cam engages with the roller during the continued forward movement of the cam and the latter ments from the dial pinions. Upon now moving the cam 14 backwardly together with the rocking frame 15, this cam does not affect the arm 13 and the parts connected therewith, but is affected by said arm at the last portion of the backward movement of the cam, at which time the back or lower side of incline 16 engages with the roller 18 which lifts said incline, and at the end of the backward movement of the cam, the latter clears said roller and drops behind the same, as

rear portion of the rocking frame 15.

shown in Figure 2, preparatory to again raising the roller 18 and connecting parts during the next-forward movement of the cam 14. I

For the purpose of permitting the front end of the cam to rise so as to clear the roller. 18', this cam is pivoted at its rear end to the The upward and downward movement of the front end of the cam is limited by means of a lug 1 9 projecting from the side of the cam and engaging with a slot in the-adjacent part ofthe rocking frame 15, as shown in Figures 15 and 34.

The rocking frame 15 is secured with its lower portion to a transverse rock-shaft 2O journaled in the main frame and provided outside of the frame with a hand crank 21, as shown in Figure 15, whereby this'shaft is rocked and the parts connected therewith are operated.

The gear segments 5 are raised to their highest position by means of a return or lifting bar 22 which extends transversely underneath all. of the arms 6 ofthe gear segments and which is connected loosely at its rear ends with the transverse rod 7 by lifting plates 23. 24 represents two shifting arms which are mounted loosely at their rear ends on the rock-shaft 20 and which support at their other ends a transverse bar 25 which transverse bar is connected at its ends, by two links 26, with thelifting plates 23, whereby upon raising the shifting arms 24, the lifting bar 22 is caused to raise the gear segments and the other par-ts connected therewith resting on said bar. Upon depression of the transverse bar 25, the lifting bar 22 is moved downwardly and the gear segments resting" thereon are permitted to move downwardly with the bar until the segments are arrested.

Each of the gear segments is yieldingly held in contact with the lifting bar 22 by a spring 27which connects the arm of the segment with the transverse bar 25. If the downward movement of the gear segment is arrested while the shifting arms 24 continue to move downwardly, the lifting bar 22 is v moved away from the underside of the arm of the gear segment and the spring 27 is strained. The transverse bar 25 is arranged at one end in a segmental notch 28 formed in the front part of the rocking frame 15, shown in Figures 2, 7 and 15, and its opposite end is arranged in a similar segmental notch 28, formed in a rocking frame 29 (Fig. 15) which is secured to the operating shaft 20 on the left-hand side of the machine. The rocking frames 15 and 29 together with the operating shaft 20 constitute the main or universal operating frame of the'i'nachine.

When the machine is at rest, as shown in Figure 2, the transverse bar 25 engages with the front side of the notches 28 in the rocking frames 15 and 29. Upon turning the rocking shaft 20 forwardly by means of its handle 21 in the direction of the arrow, Figure 2, the rocking frames are moved forwardly during the first part of the movement independ ent of the transverse bar 25. The latter remains at rest until the inclined front end 16 of the cam 14 has raised the arm 13 and moved the gear segments into engagement with the dial pinions, during which movement the rocking frames move idly the extent of their notches 28 along the ends of the bar 25 without disturbing the latter. After the gear segments have been engaged with the dial pinions, the continued forward move ment of the rocking frames causes the rear ends of their notches 28 to engage with the bar 25 and depress the same, thereby causing the lifting bar 22 to be moved downwardly and strain the springs 27. This causes all of the gear segments which are free, to be moved downwardly and to continue their downward movement until they are arrested. During the downward movement of the gear segments, while they are in engagement with the dial pinions, the'latter and the dials connected therewith are turned in the direction of the arrow, Figure 7, until the downward movement of the segments is arrested. The extent which each dial is turned depends upon the position in which the downward movement of its operating segment is arrested. After the segments have been arrested in their downward movement, they remain in this position while the rocking frames. complete their forward movement. At the end of the forward movement of the rocking frames, the roller 18 of the rock arm 13 drops off from the rear end of the-concentric part of the cam 14, thereby allowing the springs 11 to pull the gear segments rearwardly out of engagement with the dial pinions.

Upon now turing the rock-shaft 20 backwardly by means of the handle 21, the rocking frames are moved backwardly until the front ends of the notches engage with bar 25. 'When the latter is so engaged it is moved backwardly with the rocking frames to the end of their rearward movement which causes the transverse bar 25 to lift the lifting bar 22 and the gear segments which have been depressed, into their highest or normal position. During this upward movement of the depressed gear segments they are out of engagement with the dial pinions, whereby the dials are not turned backwardly with the segments, but remain'in their shifted position.

30 represents a number of elbow-shaped controlling arms, which form part of the devices whereby the downward movement of the registering gear segments is controlled. One of these arms is arranged along the lefthand side of each. gear segment and consists of an upright front part and a horizontal lower part which extends rearwardly from the lower end of the upright part, thereby leaving a clear space in rear of the upright. part of the controlling lever as represented in Figures 1, 2, 7, 14, 39 and 10. The rear end of the lower part of each controlling arm is mounted loosely on a transverse supporting bar 31, while the upper end of its front or upright part is loosely connected with the upper portion of its companion gear segment. This loose connection permits the controlling arm and the gear segment to swing freely about their individual axes, which are arranged parallel but outof line, and also permits the gear segment to move forward and backward into and out of engagement with its companion dial pinion. In the uppermost position of the controlling arms the same bear with their upper ends against a transverse stop bar 32, as shown in Figure 2, which limits the upward movement of these arms. Each controlling arm is provided on the rear part of its upper end with a locking lug 33, and on the front part of its upper end with a stop lug 34:, both of which lugs project toward the left and are preferably stamped out of one piece with the controlling arm.

T he operation of the registering devices is controlled by a number of elbow-shaped key levers which are arranged side by side and pivoted to a transverse supporting rod 35. Each key lever is provided with a lower actuating arm 36 which projects forwardly and an upper stop arm 37 which projects upwardly along the left hand side of one of the controlling arms and gear segments, as represented in Figures 2, 7, 14 and 39. Each of these key-levers is provided on the rear side of its'stop arm with a locking shoulder 38 which is adapted to engage with the locking lug 33 of the controlling. arm when the latter is elevated into its highest position and the key-lever is in its frilly retracted position, as shown in Figure 2. When the parts are in this position, the key lever holds the controlling arm against downward movement and the latter holds the gear segment against downward movement. If the gear segment while so held against downward movement is moved forward into engagement with the adjacent dial pinion, and the rocking frames are turned forwardly for depressing the gear segment, the spring 27 of this segment will be strained without,

however, shifting the segment. At the end of this forward movement of the rocking segments, the roller 18 of the rock arm 13 drops off from the rear end of the cam 14, the gear segment is moved reai'wardly out of engagement from the dial pinion and then the rocking frames move backwardly without having shifted the dial.

Theupper arm of each key lever is provided on its front side with a vertical series of differential stop shoulders 39, which are arranged step fashion and extend from the upper end of this arm downwardly and forwardly thereon or in other words the stop shoulders 39 are arranged radially out of line with one another and dilferent distances from the pivot of the key lever. These stop shoulders of the key lever are'adaptedto be moved forwardly into the path of the stop lug 34 on the controlling arm. The stop shoulders are arranged different distances from the stop lug 34 of the controlling arm,

so that by moving different stop shoulders of the key lever into the path of the stop lug of the controller arm, the latter and the gear segment connected therewith may be arrested at different points in their downward movement. The uppermost stop'shoulder of the key lever is most remote from the stop lug of the controlling arm and therefore requires the greatest forward movement of the key lever, in order to bring this stop shoulder into the path of this stop lug.

The stop shoulders of the key lever are so arranged that the distance from the stop shoulders to the path of the stop lug 34 gradually grows less from the uppermost stop shoulder to the lowermost stop shoulder. The relative position of the diflerent stop shoulders of the key lever is such that when its locking shoulder 38 remains in engagement with the locking lug 33 and the gear segment is simply moved into and out of engagement with its dial pinion, the latter remains at zero, if the same has not been previously moved. But when the key lever has been moved forwardly, so as to disengage its locking shoulder from the locking lug and moves one of its stop shoulders into the path of the stop lug of the controlling arm, the latter arm and gear segment connected therewith will be moved downwardly, upon moving the rocking frames forwardly, until the stop lug of the controlling arm strikes the respective stop shoulder of the key lever which stands in its path, as represented in Figure 7 whereby the gear segment while turning in engagement with the adjacent dial gear pinion, turns the same forward. By turning the key lever forward more or less and moving one or the other of its stop shoulders into the pathof the stop lug 34 of the controlling arm, the distance which this arm descends can be varied, thereby varying the number of spaces which its gear segment turns the adjacent dial.

N umber key mechanism controlling arms.

on-the rear part of the key-board and the corresponding higher numbers of the several columns are arranged likewise in transverse rows and progressively in their order toward the front end of the key-board.

Each of the registering keys is yieldingly held in an elevated position by a spring 43 (Fig, 25) surrounding the stem of the key and connected at its upper end to the key and bearing with its lower end against the bottom of the key-board. The upward movement of each key is limited by a shoulder 44 formed on the upper part of its stem and engaging with the underside of the top of the key-board, as represented in Figures 25, 26, 36 and 37.

The downward movement of all of the keys is substantially the same, but the arrangement of each column of keys lengthwise of the lower actuating arm of each key lever causes the keys to bear against the lever at different distances from its pivot so that by depressing different keys the same distance, the key lever will be turned different angular distances. The keys having the lowest numbers bear against their respective key levers nearest the pivot and consequently the levers are thereby thrown the greatest distance, and the uppermost stop shoulders are shifted into the path of the stop lug 34 of the respective The throw of each key lever upon depressing any one of its keys is so adjusted, that the proper stop shoulder on its upper arm is moved into the path of the stop lug 34 of the controlling arm and the downward movement of the respective gear segment is arrested after having turned the adjacent dial gear pinion a number of spaces corresponding to the number of the key which is depressed.

Zoose connection for segments The loose connection between each controlling arm and its gear segment, heretofore referred to, is shown in its Sll plest formin the connection between the controlling arm and the gear segment, which are controlled by the initial or lowest column of registering keys. As shown in Figures 1, 14, 28 and 40, the loose connection between the controlling arm and the gear segment of the lowest registering device consists of upper and lower faces of the arm. The

guide lugs and 46 arranged on the upper end of the segment and bearing against the upper and lower guide faces 47 and 48, which are formed on the upper end of its companion controlling arm. As the controlling arm and segment rise and fall, the guide lugs of the segment slide back and forth on the guide guide faces are so constructed that the back and forth movement of the segment on the arm is radial with reference to the dial pinion in all positions of the segment. By so forming the guide faces of the arm, the gear segment can be engaged with and disengaged from the dial pinion in all positions of the segment without disturbing the position of the dial pinion. The construction of the loose connections between the controlling arms and gear segments of all of the higher registering devices above the fractional registering device are combined with carrying devices, whereby each registering dial, upon making one complete turn, causes the next higher. dial to be turned forward one space, thereby carrying up a number from one order to the next higher order. The loose connections between the controlling arms and the segments and the carrying mechanism of the higher registering devices are constructed as follows As shown in Figures 1, 2, 7, 14 and 40, each controlling arm is provided at its upper end with upper and lower guide faces 47 and 48 and its lower guide face is engaged by a lower guide lug 46 on the adjacent gear segment, the same as in the coupling between the controlling arm and segment of the initial registering device. The gear segments of the higher registering devices are each provided with an upper guide l'ug 49 which is adapted at times to bear against the upper guide face 4? of the companion controlling arm in substantially the same manner in which the up per guide lug 45 of the fractional gear segment bears against its companion arm, the only difference being that the upper guide lugs 49 of the higher gear segments are held cut of engagement and separated by a space from the upper guide face of the companion arm when no number is carried from a lower to a higher registering device. The upper guide lug 49 is held in this elevated position above the adjacent guide face by a rocking latch 50 which'is arranged in a notch in the rear side of the gear segment and which normally projects toward the left and engages with the upper guide face 47 of the adjacent controlling arm, as shown in Figures 2, 28

and 40.

During the ordinary up and down movement of each higher controlling arm and gear segment, the latter is guided by its lower guide lug 46 and the locking latch 50 engaging with the lower and upper faces of the adjacent arm, this movement being the same as the movement of the controlling arm and gear segment of the fractional registering device. Normally the downward movement of the controlling arm is determined by the position of its companion key lever and this arm in turn controls the extent of the downward movement of the gear segment. lVhen, however, the lockin finger 50 is withdrawn out of engagement from the upper guide face 47 of the arm, the companion. gear segment is capable of moving downward independently of the arm until the upper guide lug 49 engages with the upper guide face of the arm. The extent of this independent movement of the gear segment with reference to its companion arm is equal to one tooth or space of the segment, so that by this means the gear segment is enabled to turn the dial pinion one space more than the position of the key lever permits the same to move.

The withdrawal of the locking latch of each higher registering device is controlled by the next lower registering device and the withdrawal of each latch is effected when the next lower registering device has made one complete turn and arrived at zero. -Each of'the locking latches is pivoted on the right hand side of its adjacent gear segment, so as to turn transversely with reference to the latter. The latch is turned toward the left into its operative position by a spring 51, (Fig. 8) the movement in this direction being limited by a shoulder 52 arranged on the latch and bearing against the right-hand side of the gear segment, as shown in Figure 8. 53 is an upright trip plate connected with the lower end of each latch and arranged normally at right angles or nearly so to the adjacent gear-segment, when the latch is in its operating position. 54 represents a number of upright trip arms, each of which is controlled by a lower registering device and which turns the locking latch of the next higher registering device into an inoperative 'position.- This arm is mounted loosely with its lower end on the supporting bar 35 and is provided at its upper end with a rearwardly and forwardly projecting hook 55, and in front and below said hook with a bend forming a bearing finger 56 (Fig. 23). 57 represents trip cams arranged on the left-hand side of each'registering dial pinion and connected with the adjacent pinion and dial. but separated from the pinion by an intervening space or groove. The face of each of these cams begins at its lowermost point near the axis thereof and then extends outwardly in a spiral line terminating with its highest point radially in line with its lowermost point with which it connects abruptly. The trip cam of the fractional registering device has its face divided into eight parts, each part of which is arranged one-eighth of a spa e further from the center of the cam than the preced ng part, while the trip cams of the igher registering devices each has its face lit) divided into ten parts, each part being a'r-- ranged one tenth of a space farther from.

the axis of the cam than the preceding part. Each of the trip arms 54extends upwardly along the right-hand side of the trip cam of a lower registering device and its shoulder 56 engages with the face of this card, while the hook 55 at its upper end extends toward the left and is adapted to engage with the trip plate 53 of the next higher registering mechanism. In the initial position of each trip arm, its shoulder 56 engages with the lowest part of its trip cam, as represented in Figure 2. As the trip cam is turned in the direction of the arrow, Figure 2, at the same time that its dial and gear pinion are moved forwardly b the adjacent gear segment during the a ding operation the trip arm is moved backwardly by the gradually rising face of the trip cam. During this backward movement of the trip arm, its hook engages with the trip plate 53 of the next higher registering device and is deflected toward the right thereby, the hook being sufficiently elastic for this purpose. After the hook has passed inrear of said trip plate, the hook owing to its resilience springs back to its normal position, so as to stand behind said trip plate. When the shoulder of the trip arm reaches the highest part of the face on the trip cam the trip arm has been shifted to its rearmost position. Upon now turning this cam forwardly another space together with its companion dial and pinion,

I the highest part of the cam is carried from underneath the shoulder of the trip arm and the latter is moved forwardly over the abrupt face of the cam until its shoulder 56 again engages with the lowest part of the cam face. During this movement of the trip arm, its hook strikes the rear side of the trip plate 53 of the next higher registering mechanism and turns the same forwardly, as shown in Figure 28, thereby disengaging the locking latch' from the ad acent controlling arm and permitting the gear segment carrying the trip plate to move forward one space. The forward movement of the trip arm is effected when the dial with which its trip cam is connected has made one complete rotation and again stands at zero, whereby the addition represented by this complete rotation is'carried to the next higher registering device. The forward movement of the trip arm is effected quickly by a spring 58, which connects with a stationary cross bar 59 arranged in front of the trip arms. The trip plate 53 of each registering device is so arranged and is of such length that the hook of the next lower trip armcan en-v gage with the rear side of the plate, fordisengaging its latch in any gear segment carrying the p ate. If a gear segment is locked in its highest position by reason of none of its companion keys havosition of the ing been depressed, the withdrawal of its latch from the controlling arm simply permits the gear segment to drop one space and turn its companion dial pinion forward one space, while in engagement therewith, the movement of this dial representing one number carried up from the'next lower dial. If

' wardly for effecting an addition, and if during this time the next lower registering device has made a complete turn, so as to require the carrying up of a number from the next lower registering mechanism, the latch of the higher registering device will be withdrawn while the same is efiecting its addition, thereby causing the segment to descend and turn its dial one space in addition to the spaces corresponding to the depression of its respective key. When the locking latch has been with drawn so as to permit a gear segment to move downwardly one space farther than its controlling arm, the latch remains in this position during the subsequent upward movement of the arm and the segment until the.

upward movement of the arm is arrested by striking the stop bar.32 and the gear segment continues its upward movement independent of the arm the extent of one space. The gear segment has now reached its highest position and its latch is again swung automatically by its spring over the controlling arm. The controlling arm and gear segment now remain in this relative position until another number is to be carried up from the next lower registering device.

l/Vhen the controlling arm has been retracted to its highest position, the adjacent key lever is moved into its normal retracted position, so that its locking shoulder 38 engages with the locking lug 33 of the controlling arm and locks the latter against downward movement. The return movement of each key lever is preferably effected by a spring 60 which connects the upper arm of the key lever-with the transverse shaft 9, as shown in Figures 2 and 7, or some other convenient part of the machine. The lower guide lug of the gear segment compels the arm to rise with the gear segment and avoids displacement of these parts with reference to each other, and also serves as a stop to limit the upward movement of the gear segment.

The gear pinion and the co-operating gear segment of the fractional registering device are so constructed that the fractional dial makes one rotation whenever it is moved forward eight spaces. After the fractional dial has made one rotation the whole number rep resented by this rotation is transferred by the first carrying device from the registering mechanism of the fractional dial to the next next lower dial and is incapable of being" operated directly from the key-board because it is not provided with a key operating mechanism.

The mechanism whereby the dials are all turned back to zero or the place of beginning after the addition of numbers has been completed is constructed as follows:

61 (Figs. 2 and 7 represents a series of feeling rock levers which are adapted to shift the key levers so as to permit the gear segments to descend the proper distance for resetting or restoring the registering dials to zero. One of these shifting levers 1S mounted loosely on the supporting bar adjacent to the left hand side of each of the key levers and is provided on its upper arm with a for wardly projecting feeling finger 62 and with a shifting finger 63 which extends behind the upper arm of the adjacent key lever. The feeling levers have their fingers arranged'in rear of the cams 57 and each of these levers is turned so that its upper arm moves backwardly by the upper arm of the adjacent key lever engaging with the shifting finger 63 of the feeling lever. 64 represents a transverse pull bar arranged in rear of the lowerarms of the feeling levers and connected with each of the latter by a pull string 65, as represented in Figures 2,7 and 15. This pull bar is connected at its endsto the lower end of two depending pull or rock arms 66, which are secured at their upper ends to the rock shaft 9, as shown in Figure 15. Upon turning this rock-shaft, so as to swing its depending pull arms backwardly the feeling levers .are turned by means of the springs 65 so as to move the upper arms of these levers forwardly. This movement of the rock-shaft 9, is effected by a cam 67 (Figs. 10, 19 and 33) which is mounted on the left-hand side of the rocking frame 29 and which is constructed substantially the same as the cam 14 which is mounted on the rocking frame 15. [is shown in Figures 10 and 19, this cam is pivoted at its rear end by a transverse pin to the rear portion of the rocking frame 29 and is provided at its front end with anincline or cam face 68 and in rear of the incline with a concentric face 69. The cam 67 can be raised and lowered with its front end into an inoperative or operative position, this movement being limited by means of a lug 70 arranged on the cam as shown in Figure 15 and projecting into a slot 71 in the adjacent rocking frame in the same manner in which the movement of the cam 14 is limited as shown in Figure 34.

72, Figures '10 and 15, represents a rearwardly -projecting rock-arm secured to the rock-"shaft 9 and provided at its rear end with a roller or projection 7 3 which is adapted to be engaged by the cam 67 for turning the rock shaft 9. When numbers are being added with the machine, the cam 14 is depressed, as shown in full lines, Figure 2, so as to be in a position when moved forwardly by the rocking frame 15 to engage the roller on the arm 13, for moving the gear segments into engagement with the dial pinions, and during this time the cam 67 is lifted into the position shown in full lines, Figure 10, so that when the rocking frame 29 is moved forwardly, the cam 67 will clear the roller 7 3 of the rock arm 72 and not disturb the rockshaft 9 and the parts connected therewith.

roller 18 of the arm 13 without disturbing the same, but the inclined front of the cam 67 engages with the roller 73 on the rear end of the rock-arm 72 and raises the same until this roller engages with the concentric part 69 of this cam. By this movement of the arm 72, the rock shaft 9 is turned in the direction for moving its depending arms 66 rearwardly and pulling the springs 65'rearwardly. This pull on the springs 65 causes the feeling levers to be turned until the feeling fingers of their upper arms engage with the spiral surfaces of the trip cams. After the feeling fingers bear against these cams, their movement is arrested and the continued backward movement of the pull bar 64 simply stretches the springs 65 until the bar reaches the end of its backward movement. The feeling finger of each fee'ling lever engages with that part of the surface of the adjacent trip cam which is directly opposite the feeling finger, and as these trip cams are turned with the adjacent dial they present different parts of their spiral surfaces to the opposing feeling fingers, which causes the forward movement of the upper arms of the feeling levers to be arrested in difierent positions when swung forwardly. During the forward movement of. the upper arm of each feeling lever, its shifting finger 63 engages with the rear side of the upwardly projecting arm of the adjacent key lever and moves this arm forwardly. The construction of the parts is such that the Spiral surface of the trip cam bears a definite relation to the step-shaped series of' stop shoulders on the upper arm of the key lever.

When the feeling finger of the feeling lever, uponbeing moved forwardly, bears against the lowest .part of the adjacent trip cam, the.

controlling arm. This forward movement of the feeling lever and that of the upper arm of the key lever is gradually reduced as the progressively higher parts of the trip cam are presented to the feeling finger, and when the highest part of the trip cam is presented to the feeling finger, the feeling lever is prevented from moving forward at all and the upper arm of the key lever is not moved with its locking shoulder out of engagement with the locking stop of the controlling arm and consequently the companion gear segmentconnected therewith is held against downward movement. After the rocking frames 15 and 29 have been turned forwardly sufiicientl to engage the several feeling fingers of the eeling levers with their respective trip cams, the rear ends of the segmental notches 28 in the rocking frames engage with the cross bar 25 and depress the same, thereby moving the lifting bar 22 downwardly and at the same time pulling down the springs 27. V This downward pull on these springs causes each spring to pull its respective gear segment down as far 'as possible, and after the downward movement of the segment has been arrested the continued downward movement of the cross bar 22 together with the rocking frames simpl stretches these springs until this bar reac es the end of its downward If a gear segment is locked in its uppermost or Zero position itsspring 27 will be stretched its fullest extent, whereas, if a gear segment moves downwardly more or less before it is arrested by its shifted key lever, the spring 27 Will be stretched less in proportion. This downward movement of the gear segments, which are free to move in this direction, takes place while the gear segments are in their retracted position and out of engagement from the dial pinions, so that the dials are not affected by this movement of the segments.

After the rocking frames have reached the end of their forward movement and the roller 73 has dropped off from the rear end of the concentric portion 69 of the cam 67, the gear segments are moved forwardly by operated mechanism into engagement with their respective dial pinions and are held; in this position during the entire subsequent backward movement of the rocking frames, which is effected by operated mechanism. During the backward movement of the rocking frames, the gear segments are raised to their highest positions, while in engagement with the dial pinions by the rod 22 and connecting parts and turn thedials backwardly. At the end of the upward movement of the gear segments the latter are released, so as to permit them to move into their retracted osition, out of engagement from the dial pinlons.

During this operation, those gear segments which are held or locked in their highest positions, by reason of their dials being at zero, are simply moved forward at the end of the forward movement of the rocking frames, so as to engage with their respective dial pinions and are again moved backwardly out of engagement therefrom at the end of the backward movement of the rocking frames, without disturbing their respective dials. Each of the unlocked gear segments is moved downwardly a number of spaces corresponding to the number which is registered on its dial, the extent of this movement being controlled by the companion trip cam which arrests the forward movement of the key lever, through the medium of its feeling lever, when the proper stop shoulder of the key lever has been presented to the controlling arm.

Upon now moving the gear segments forwardly in their variously depressed positions and then raising themto their highest position, each depressed gear segment will turn its dial backward the same number of spaces that the gear segment was depressed. Inasmuch as each gear segment was permitted to descend by its trip cam, feeling lever and key lever the same number of spaces as the number indicated on its dial, the gear segment subsequently moves upwardly the same number of spaces before reaching its highest position, thereby turning its dial backwardly the same number of spaces and restoring the same to zero. When all of the dials have been returned to zero, the shoulders 56 of all the trip arms engage with the lowest parts of all of the trip cams 57.

The cams 14 and 67 are provided with a longitudinal slit 74, as shown in Figure 33, so as to facilitate the manufacture of these parts.

The mechanism whereby the positions of the cams 14 and 67 are reversed preparatory to restoring the dials to zero is constructed as follows:

The cams 14- and 67 drop into their operative position by gravity. Each of these cams is provided in rear of its pivot with a tail 75 which is depressed when it is desired to lift therespective cam into its inoperative position.

76 is a shifting lever which is pivoted at its lower end an is normally turned so that its upper and lower arms and arranged with its upper arm in rear of the tail on the cam 67 and normally held in engagement therewith by a spring 79, as shown in that figure. 80 represents an elbow lever pivoted below the bottom of the keyboard, as represented in Figure 10. 81 represents a main line or cord which is connected with the lower arm of the elbow lever 80 and which is provided at its rear end with two branches 82 and 83. The branch 82 connects with the shifting lever 76 above its pivot, and the branch 83 connects with the shifting lever 78 below its pivot. 84 represents a shifting key having a depending stem which is guided in top and bottom of the key-board and which bears with its lower end against the upper arm of the elbow lever 80. Upon depressing the key 84, the elbow lever 80is turned, so as to draw the cords or lines 81, 82 and 83 forwardly, thereby moving the upper end of the shifting lever 7 6 into engagement with the tail of the cam 14 and lifting the same into an inoperative position, while the shift ing lever 78 is moved rearwardly with its upper arm from the tail of the cam thereby allowing the latter to drop into its operative positlon. Upon depressing the gear segments while the parts are in this shifted position, the segments move downwardly out of engagement with the dial pinions.

After the gear segments have been depressed they are moved forwardly into engagement with their respective dial pinions by an elbow lever 85 which is connected with its lower arm by a line or cord 86 to the rod or bar 7, as shown in Figure 10, or to one of the rock arms 8. The elbow lever is turned in the proper direction for this purpose by a shifting key 87 having a depending stem which is guided in the top and bottom of the keyboard and which bears against the upper arm of the elbow lever 85. After the gear segments have been moved forwardly into engagement with the dial pinions, while in the depressed position, the gear segments are retained in this position, and at the same time raised until they reach their uppermost position. whereby the dials are turned to zero. The shifting key 87 is now released which permits the spring 11 to move the gear segments rearwardly out of engagement with the dial pinions. The key 84 is also released, thereby permitting the shifting levers 76 and 78 to resume the positions shown in Figures 2 and 10, leaving the machine in position to resume adding.

-Each of the dials 2 is held against turning when out of engagement with its actuating gear segment by means of a detent pawl 103 which engages with the front side of the companion gear pinion, as shown in Figures 2, 7 and 14. The pawls 103 of the several gear pinions are mounted on a transverse pawl bar 104, which is supported at its ends by means of two pawl arms 105, which turn loosely upon the supporting rod on bar 35 of the key levers, as shown in Figures 2 and 14. The pawl arms are moved rearwardly for engaging the pa'wls of the bar 104 with the gear pinions by means of springs 106, as shown in Figures 10 and 14. These springs are connected loosely at their rear ends to the rock-shaft ,9 and at their front ends to the pawl arms 105. During the forward movement of the gear segments preparatory to turning the dial pinions, the detent pawls are swung forwardly out of engagement with the dial pinions by means of two shifting rods 107 which are connected at their rear ends to opposite ends of the transverse rod 7 or some part moving therewith and each of which is provided at its front end with a fork or bifurcation 108, which engages with a pin or shoulder 109 on the pawl arm arranged on the adjacent side of the machine, as shown in Figures 2, 10 and 14. As the gear segments move forward into engagement with the gear pinions the shifting rods 107 move the detent pawls 103 out of engagement with the dial pinions and when the gear segments move backwardly the detent pawls are again engaged with the dial pin- 10ns by the springs 106.,

Recording mechanism For this purpose 'of recording the numbers which are added together by the above described mechanism a recording mechanism is provided which is constructed as follows 140 (Figs. 1, 2, 10, etc.) represents a print-- ing roller or platen which is arranged transversely in the upper, rear part ofthe machine and under the lower side of which the sheet or other article is placed which receives the record. 141 represents a number of type segments which are arranged transversely side by side below the platen and which are pivoted at their front ends to the supporting bar 31 upon which the rear ends of the controlling arms are pivoted. Each of these type segments is provided at its rear end with a segmental row of type carriers 142, which are capable of moving radially back and forth on the type segment.

Each of the type carriers is priovided at its rear end with a type and is guidedupon the type segment by means of screws or rivets 143 (Figs. 30 and 31) secured to the type carrier and arranged in radial slots 144 formed in the type segment, as shown in Figures 2, 3

and 31. Each of the type carriers is held in point or line, and upon striking the back or I inner end of the type carrier, when the same is in line with the printing point the type carrier will be driven outwardly and its type will produce an impression on the sheet supported by the platen. After the carrier has received the blow for driving the same against the platen, the carrier is again quickly retracted to its innermost position by means of its spring.

Each of the type segments is connected with one of the controlling arms, so that upon depressing a controlling arm andthe registering gear segment connected therewith, the companion type segment will be raised and present one of its type to the printing point.

For convenience in operating the machine,

the keys are separated a considerable distance on the key-board and in order to produce a. compact record, the printing segments are arranged closer together than the keys and the registering mechanism. In order to permit this arrangement, each type segment and its corresponding controlling arm are connected by a connecting arm 146, as'represented in Figures 1, 2 and 39. The connecting arms of the central controlling arms, and type segments are comparatively straight, but the connecting arms of the outer type J segments and controlling arms are arranged obliquely, the degree of this obliquity gradually increasing from the central type segments and controlling arms in opposite directions toward the outer type segments and controlling arms, as represented in Figure 1. The connecting arms 146 of the outer controlling arms are arranged in the spaces be-. hind the upright parts and above the horizontal parts of the controlling arms, thereby permitting the inner controlling arms to move-up and down without interfering with the connecting arms 146 of the outer controlling arms.

The types on each type segment are arranged tocorrespond with the teeth and numbers of its companion gear segment and registering dial, the zero type being at the upper end of the series and the progressively higher digits arranged in their order downwardly from the zero type. \Vhen the registering gear segment is in its highest position it presents its zero tooth to the dial pinion, and the type segment which at this time is in its lowest position presents its zero type to the printing point. Upon depressing a gear segment so as to present one of its higher teeth to the dial pinion, its companion type segment is raised proportionally and presents a corresponding higher numbered type to the printing point.

147 represents a number of hammers whereby the type carriers are struck for driving the type against the platen. One of these arranged in front of the series of types and in line with the printing point of the platen.

Upon shifting the type segment so as to bring one or another of its type carriers to the printing line and then operating the hammer, the latter delivers a blow against the inner end of the particular carrier which is at the printing point and produces an impression of its type on the platen. The several hammers are pivoted on the transverse rod 12, arranged in rear of the segments; and each of the hammers is yieldingly held in its forward position by a spring 148 connected at its lower end to a cross bar 1 19 and at its upper end to a depending arm 150 on the hammer.

151 represents a vertically movable trip bar or rod which is arranged transversely below the hammers and whereby the latter are operated. This bar is supported at its ends upon the rear ends of rock arms 152 which turn loosely with their front ends on the rod 31 supporting the type segments and controlling arm'.

153 (Figs. 2, 3, 6 and 17) represents a number of hammer or trip pawls, whereby the hammers are retracted preparatory to delivering a blow against the type carriers which are at the printing point. One of these pawls is arranged adjacent to each hammerand pivoted loosely at its lower end to the trip bar 151, and its upper end is provided on its rear side with a downwardly facing hook or shoulder 154, and above said shoulder with a trip face 155, as shown in Figure 17. Each of the hammers is provided in front of its pivot adjacent to the upper end of the hammer pawl with a lower trip lug or shoulder 156 and an upper trip lug or shoulder 157. When the parts are at rest, the hammer pawl 153 is raised into its highest position and the hammer is in its normal position with its lower trip lug 156 below and in rear of the hook of the hammer pawl and with its upper shoulder 157 in rear of the trip face of the hammer pawl, as represented in Figures 2, 3 and 17.

Upon shifting the hammer pawl rearward- 1y, while the parts are in this position, so that its hook overhangs the lower shoulder 156 of the hammer, and then pulling the hammer pawl downwardly, the hook of the hammer pawl engages with the lower shoulder of the hammer and turns the same so that its head is retracted from the type carrier at the printing line. "As the hammer moves downwardly with the hammer pawl, the uphammers is arranged adjacent .to each type segment and is provided with a head which is per shoulder of the hammer comes into engagement with the trip face of the hammer pawl and during the continued downward
